Siemens Soft Starter 3RW3017-1BB14

The Siemens 3RW3017-1BB14 is a SIRIUS soft starter from the 3RW30 series, designed for the smooth starting of three-phase induction motors to reduce starting torque and inrush current. 

Specification:

• Product Type: SIRIUS Soft Starter.
• Size: S00.
• Rated Operational Current (Ie): 12.5 A (at 40 °C).
• Rated Power: 5.5 kW at 400 V (3 kW at 230 V.
• Operating Voltage (Ue): 200-480 V AC (three-phase).
• Control Supply Voltage: 110-230 V AC/DC.
• Connection Type: Screw terminals.

The device gradually ramps up the motor voltage, ensuring a smooth start that reduces mechanical stress on power transmission components and protects the power grid from harmful current surges.
